Abstract (ztlthb)
Based on the technical analysis and calculation of related parameters of the model airplane, the corresponding injection molding manufacture process was selected.The selected
plastic injection moulding machine model was XS-ZY-125 and the injection mode of one mold to one model was adopted in the production.(ztlthb)
Considering the structural characteristics of aircraft models, flat parting surface was adopted as it was easy to release the mold.(ztlthb)
Point Injection mouth was the type used in the injection, which guaranteed the quality and
appearance of the aircraft model and it could pull off easily when releasing so it was easy to realize the automation.For the molding of the tail of the aircraft model the commonly used lateral parting type and the core-pulling operation were employed. At the same time,
design and calculation of cavity size were conducted. The Launching mechanisum was the commonly used push lever design combined with the clamping of the guide pin bushings guiding mechanism. In terms of software applications, integrated application of Auto
CAD, UG software to design the overall structure of the injection mould for the aircraft
model and analysis was introduced. The three dimensional parts and tooling assembly
drawing of aircraft models and a two-dimensional graph could be quicly generated with the software, which could clearly illustrate the aircraft model, the structure of injection
mold parts and theassembly. In terms of mould processing, the development of a dynamic
simulation of cavity processing was designed with detailed determination on the amount
of milling cutters, feed allowance.(ztlthb)

脱模剂一般使用方法；1．先用适当的洗模水彻底的清洗模具,以祛除先前残留的脱模剂和其他的污染,再用干净的布和毛巾擦干.2． 使用前请先将桶搅拌摇下.如有沉淀.摇匀后不影响效果3． 可以使用有空气辅助的喷涂设备,亦...

世事无绝对,要看你的什么产品,什么材料而定,一般来说这种调机方法不科学,但不科学的方法用在某种特定的地方变得科学了；比如软质的材料,如果你采用2段或多段调机,还加上保压,这样你打出来的产品就很难看了.
